It's My Fault, but…

I have uploaded two pics within that past few days that were way too big. At the time of upload I clicked ‘cancel,’ but no cancel. So, I wish there was at least a way for users to swap a photo, or allow a time period where the picture can be deleted or replaced/updated. I realize this would include a DB update that may not currently be available to users, but I wish…
Thanks,
